Identical twins occur by chance when ONE egg randomly divides into two embryos. Same DNA, yes but different gene expression, growth patterns, medical conditions, and everyday life is why some identical twins don’t look exactly alike. Fraternal twins happen when the body releases TWO eggs during one cycle. If both eggs are fertilized, it results in two babies. Identical twins aren’t genetic, whereas fraternal twins can run in families and are inherited from the mother’s side. #cerebralpalsy #hie
